Nut-lock.



Locks,o1t whichthe following is a specifica LEWiS w. HUB R; o F 'BnooKvI'LL- ,PENNSYLVANITA:

T0 all whom it ma'y coitcerni Be it known that' I, LEWIS W. HUBER, a citizen of the United States, residing at Brookville, in the county ,of Jeiferson and State of Pennsylvania, have invented .cer-" tain new and useful Improvementsin .Nut-

tion, reference being had to the accompanying drawlngs.

This invention relates to improvements in; nut locks, and particularly for locking the nuts of railway joints, the object of the 111-- vention being to provide improved devices which may be employed at a railjoint for locking the nuts on the bolts, so that they cannot become loosened or detached, the invention consisting 1n the construction, com-1 blnation and arrangement of devices, hereinafter described and claimed. o

In the accompanying drawings-Figure 1 is a side elevation of a rail joint provided with my improved nut locking do vices. Fig. 2 is a horizontalsectional viewof the same on the plane indicatedby the line aa of Fig. 1. -Fig. 3 is a vertical transverse sectional view of the same on the plane indicated, by theline 71+?) of p from the bolt and then'turn the cam spring tothefposition shown in dotted lines in Fig. 2. The locking plate is then free to move:

outwardly in the link sowthat it can'be disposed the required inclination with Fig. 1. l r 1 I For the purposes ofthisspecification, the meeting ends of a pair of rails are shown at 1, the usual fish plates being indicatediat 2, and the usual bolts being indicated at 3.

Inv accordance with my invention, 1; provide a base plate #lfof a size and shape adapting it to fit on one of the fish plates and provided with openings 5, through which the bolts 3 extend, This'base plate may extend across the joint between the" rails and is provided at its centerwith a transverse semi-cylindrical offset 6,which provides a groove Ton its'in'ner side. One

side of a link 8 is placed in the said groove so that the link is pivotally and detachably connected to the locking plate. A cam spring 9, ispivotally connected at one end as at 10, to the outer side ofthe link. This cam spring has a curved substantially semicylindrical inner end'portion 11, from which extends a spring arnr12. I also'provide a locking plate 13, which is provided with in-turned side flanges 14;, thereby forming a channel 15, for-the reception of the nuts 16 Q ofthe bolts, the channeled side of the said locking plate being presented ,to the base plate 4. Thislocking plate extends through the link 8, and is provided with'slots l7 Specification of Letters Patent. ii Patent Application filed April 12, 1911. serial No. 620,587

fromtheends ofthe bolts.

understood that after the base plateshave been removed, the link can be disconnected j 1, from the base plate owing to the provision edJe' 2. 5

adapt'ed to engage one of the bolts. By the provision of the open slot' 1S and the closed slots 17, the channeled locking plate; may be readily placed on the outer sides of the nuts and its slots en'gagedby the threaded pros jecting ends of the bolts,v andwit will be i forthe reception ofthe projecting threaded ends of the bolts.

2. In combination with arail joint havQ ing fish plates and bolts, a base platejbearsing against one of the fish plates, and under the nuts, a link 'pivotally connected tothe f baseplate, a Lcam'spring plvotally connected" side of the locking plate, and to engage its spring arm with one of the bolts.

3. In combination with a rail joint having fish plates and bolts, a base plate bearing against one of the fish plates, and under the nuts, a link pivotally connected to the base plate, and detachable therefrom, a cam spring pivotally connected to the outer side of the said link, and provided with an arm, and a channel locking plate adapted to be passed through the said link, and disposed with its channeled side on the outer sides of the nuts, said locking plate having slots to clear the projecting ends of the bolts, the said cam spring being adapted to be turned to bear on the outer side of the lockingplate, and to engage its spring arm with oneof the bolts.

In testimony whereof I hereunto afiix my signature in the presence of two witnesses.
